Air Bubbles Are Bad..

[zeo]

From what I've read now; for a marine aquarium atleast air bubbles are bad.. the main cause of salt creeps in an aquarium.

I know my protien skimmer produces bubbles inside the unit, but when the water returns back to my aquarium. I often see a few bubbles.
Majority of theses are prob caused by the water flowing out of the skimmer into the main aquarium and the splash causing bubbles. Like a waterfall.

Are these bubbles also bad? Should I try to minimize it some how.
Having a juwel aquarium, the max water level can only go so high, so there is a height difference of about 8-10cm between the skimmer (sitting on the side of the tank) and max aquarium water level.

Btw salt creeps are white lines that go across the inside of the aquarium. Both in and out of water)

If you look at your tank, can you see its full of bubbles? If not dont worry!

I was worrying when I was seeing a few and spoke to my LFS, then saw some examples of bubbles and relaxed as mine was a million times better!

big bubbles that pop and spread water all along the lights etc are bad, a small amount of micro-bubbles that dont really pop any water out of the tank are not really salt creep makers.

a few micro bubbles are fine, no worries

the only problems i find with micro bubbles is the clowding effect they give to the tank. it pees me right off i tell you. think you will find most corals will be ok with micro but if you can get rid of them it would be for the best.

Agreed, a few are fine, a tank that has so many bubbles you can't see into it would be bad
